' heel portion of a sole can be properly trimmed to fit a full breastedor Louis heel, so that the heel when seatedthereon will make a close fitwith the counter portion oi the shoe upper, the trimming beingpreferablymade after the sole is attached to the shoe. A further object is toprovide aheel seating mechanism which can be readily attached to ormounted for operation on an ordinary die press or the like so that theattachment can be easily operated by powerif desired.

The attachment in brief comprises a movable punch plate cooperating witha fixed die plate to trim the heel portion of a sole to fit acorrespondingly shaped recess in the fulh breasted or other heel; thedie plate being preferably tapered on its under side to a thin edge atits front side so that the unattached heel portion of a shoe sole can beeasily slipped thereover when positioning a shoe thereunder. The punchplate is normally spaced from the die plate by springs. A yieldablestripper plate is provided to clear the punch ofwaste material.. The dieplate can be depressed by manually operated means, but is preferablyactuated by a reciprocating plunger which may be automatically stoppedby ordinary means at the end of each reciprocation, to enable soles tobe positioned under the die plate for operation thereon, and removedafter the operation and replaced by another to be operated upon. Beneaththe die plate is a gage or stop again-st which the shoe ispositionedpreparatory to being operatedupon. In operation a shoe with asole attached is positioned againstthe gagejbeneath the die plate thethin edge of the die plate entering between the unattached end of theheel portion of the sole and the heel of the shoe as the latteri-spositioned against the gage, so that the heel portion of the soleoverlying the die plate and then thepunch plate is forced down andpunches surplus material from the heel portion of the sole thusproperlytrimming it to fit the heel. The present invention hasparticular reference to the construction of the said die plate, thecooperating punch plate, the means for stripping the'waste material fromthe punch and preventing it piling up between the punch and die plates,and the gage for positioning a last carrying the shoe beneath the dieplate.

Thesaid devices can bereadily attached to various forms of punchpresses, and in the machines shown the devices are mounted on anordinary typeotpunch pressso that they they may be actuated by themechanism of said press. c I will explain the invention in detail withreference to the accompanying drawings and epitomize inthe claimsthenovel features .of construction andinovel combinations of parts forwhich protection is desired.

In said drawings;

Fig. 8 is a detail view of the heelportion of a sole trimmed to fit a FLouis heel. Fig. 9 .is a detail ofthe waste cut from the heel portion of a sole- Fig. 10 is a detailsection through one of the die and punch plate connections.

The machine illustratedis adapted :to trim the heelportions of .thesoles to fit Louis heels. The-die plate 1 is provided with a die opening1a that corresponds in size and shape with the heel portion of a sole.adapted to fit a Louis heel (as shown at HinFig. 8) and this die isadaptedto cooperate with. a correspondingly shaped complementary punchQaonthe lower face ofthepunch' plater2.

The forward edge of the die plate 1 intermediate its ends is preferablybeveled on its upper side, being thinnest at its front edge 1 0 as shownin Figs. 4 and 6, and tapering rearwardly and downwardly to its rear andthis thin edge of the die plate enters between the unattached heelportion H of the sole, and the body of the shoe when the heel portion ofthe shoe is entered between the die plate and against the gage 5 asindicated in dottedlines in Fi This greatly facilitates the operation ofthe machine and relieves-the operator from the necessity of lifting theunattached heel portion H of the sole. from the shoe in order tocorrectly position it between the die plates l and 2. The die plate ispreferably provided with depending flanges as at 16 which depend intoand engage the sides of a slot in the top plate 6a fastened to themembers 6; which members 6 have rearwardly extending portions 6]) whichmay bebolted to the upright U of the punch press below the plungerthereof. The said die plate is positioned by means of clamps 0 bolted tothe plate 6a as shown so as to properly position the die plate thereonand hold it rigidly in position beneath the reciprocatory plunger P ofthe press. V

The punch plate 2 is mounted above the die plate but accuratelypositioned and guided in its movement relative to the die plate by meansof stud bolts 1w and3 fixed to the die plate and projecting throughguide openings in the punch plate; which is normally spaced from the dieplate by springs l strung on the stud bolts 3 between the die and punchplate.- The separation of the die plate from the punch plate is limitedby'suitable adjustable stops, such as nuts 3a on the threaded upper endsof the studs 8. 1

' Preferably the die plate is also provided on its upper side withupstanding flanges 16 at opposite sides of the die opening and spacedapart sufiiciently to permit entrance of the untrimmed end 'of the heelportion of a sole therebetween and between the die plate and the punchplate. These flanges may be bored for the reception of the studs 1w and3 and the upper ends of these bores for studs 3 are preferably enlargedto receive the lower ends of the springs 4 (see Fig. 10). Thisconstruetion will obviate any possibility of the end of the sole ortrimmings being caught by or bea .7 tween the springs.

' has a lateral extension or wing 26 at each side The punch 2a of thedie plate)? preferably of the front end thereof and these are adapted tocooperate with the front edges 1 0 of the die plate at opposite sides ofthe front of the die opening so that the punch will cut ahorse-shoeshaped waste portion H from the heelportion of the sole (seeFig 9) forming the'tongue H andthe shoulders h 011' theheel portion ofthe sole, as shown in Fig.8, at oneoperation.v The punch can risesufficiently to give ample clearance between the opposed faces of thepunch and die for the entry of the heel portion of;

the sole therebetween but it need not rise above the tops of the flanges1c of the die plate.

Yieldably attached to and movable with the punch plate is a stripperplate 14 which has an internal recess adapted to fit around the punchand permit the latter to move through the stripper plate or the stripperplate to move upwardly relatively to the surface of the punch; and thisstripper plate is attachedto and supported by pins 14a which extendthrough openings in the punch plate and through. the base of the anvilplate 12 mounted on the punch plate 2; and springs 14?) are strung onpins 14a between the stripper plate 14 and the punch plate 2. 77

Upon the punch plate is an anvil plate 12 which may be formed integralwith the punch plate, but preferably is formed sepa rately from, thepunchplate and is fitted in a transverse groove therein andmay besecured thereto by pin 12c and bolt 12d as shown; and this anvil platehas a centrally Preferably and as shown in the drawings this gagecomprises a plate 5 having a concave recess inits front edge, and isslidably supported in guide bars or flanges 6/ at taclied to theunderside ofthe plate 6a at opposite sides of the recess therein andbeneath the die plate 1 (see Figs. 1, 4t and 5). As shown this plate 5has a depending lug 5a on its rear end andto this lug is pivoted one endof a link' 156 the otherend of which is connected to one end of a crankarm 15a on "a rock shaft 15, which is ournaled in the side plates 6,andon the one end of the shaft 15 outside ofthe plate 6 is fastenedanarm 1565 through the free-end of which-passes a hand screw 156. "Ifhis hand screw is adapted to engage the side of the adjacent. plate 6.

the shaft 15and gage plate will be locked in adjusted position. 7 i

' The heel portion'of a previously shaped sole can be inserted'betweenthe die and. i

punch plates'when the latter is in raised position;(see Figs. 1 and 4c)and'then the punch plate forced down and its punch cooperate with thedie opening to cut'an approximate horse shoe shaped waste portion H fromthe heel portion of the sole, leaving the heel portion with anapproximately oval-shaped tongue H as shown in Fig. 8. Such heel portionafter being thus shaped is adapted to enter a corresponding recess inthe upper portion of the heel which is subsequently fastened to theshoe.

The punch plate may be forced down or toward the die plate so as tocause the punches to operate with the dies by any suitable manuallyoperable means, but preferably power means are employed for thispurpose.

The plunger P can be reciprocated by any suitable means, as commonlyused in punch presses, from or by the shaft T on which is rotatablymounted a wheel W that can be locked on or disengaged from the shaft bymeans of clutch member C. The clutch member can be thrown into and outof operation by a stop 1) which may be moved into operative position bymeans of trip rod E connected to a treadle, not shown. Such operatingand controlling devices for plunger P are common in the art (see forexample Ronan Patent #956,422 or Allen Patent #1,027,638) and form nopart of the present invention and further description thereof isneedless.

When the plunger descends the stripper plate 14 will be arrested by theheel portion of the sole and will clamp the portion severed by the dieand hold the same against the die plate while the punch descends andsevers it from the sole; and when the punch rises the stripper plateforces the severed portions oil' of the punch. When the trimmed sole isremoved the severed portion remains on the die plate and between theflanges 16 thereof but the next sole inserted between the flanges andover the die plate pushes the waste severed portion rearwardly out frombetween the flanges, and it is discharged into a chute 16 by which itmay be conducted to any suitable receiver. The stripper plate preventsthe waste material from piling up between the punch and die plate andkeeps it flat on such die plate.

The aforesaid devices may also be used for shaping the heel portion ofthe soles attached to the upper of the shoe before the heel portions arethemselves secured. When so used a last with a shoe thereon having itssole partly attached but its heel portion loose, is positioned beneaththe die plate with the loose heel portion of the sole overlying the dieplate and between the latter and the punch plate as indicated at S inFig. 4. When the die descends the plunger is operated to engage theanvil plate .12, Fig. 2 to depress the punch plate and trim the heel, asshown in Fig. 8, or in other desired form.

The operation of the devices will be clearly understood from theforegoing description and the drawings. It is obvious that theattachment can be readily placed on various types of punch presses, sothat the die plate machine, a'press hav- 2.
